Added support to CMake and autoconf for unit tests in clang-tools-extra. A
dummy test exists for now until more meaningful tests can be written.

NOTE: You may need to run 'make clean' or 'ninja -t clean' etc!!! This
is due to really nasty bug/interactions between
CMake/configure/make/Ninja/LIT...
This commit tries to back out the support for generating test cases as
part of the build system due to the issues I brought up in post-commit
review:
1) It adds a *lot* of complexity and fragility to the build system. See
the number of commits required to try to get all the bots happy.
2) It isn't really necessary -- we can already run scripts to generate
things with the RUN lines of a test.
3) It makes the tests somewhat harder to debug as they cross between
more domains.
4) In almost all cases it isn't really needed or it can be done directly
using the preprocessor.
I should have been more proactive reviewing this, and I'm really sorry
about the churn here. =/ To help keep track of what commits are going

There were several trivial or cleanup changes to the lit files or other
files. Some of these looked ok, but I didn't try to tease them apart...
Edwin, if you know what to look for, please carry on with the cleanups
there, and sorry for hosing stuff here but I'm not much of a Python
person, and so I was erring on the side of cautiously backing out the
change.
I've tried to preserve the test changes everywhere I could, but review
is appreciated here in case I missed some.
I then re-wrote the tests to use the preprocessor rather than python to
expand to the various bits of code. The nicest part of this is that now
all the files are just C++ code. They edit and behave like C++ code,
etc. RUN lines with different -D flags are used to run the same test
over multiple different configurations, and includes bracketed in
special defines are used to flesh out a collection of standard interface
stubs to test interactions between pieces. These probably aren't perfect
yet, but I think its an improvement (at least in terms of build system
complexity) and will hopefully be a useful demonstration of the
technique I prefer for these types of tests.

To afford hand-written tests access to any auto-generated headers, a
lit.site.cfg is now created for cpp11-migrate's test directory providing a new
config.substition. Tests can refer to %gen_root in the LIT script.
Removed use of --param clang_site_config. Not necessary when running
tests using the build system.

* Fixed a comment typo
* Changed 'autogen' to 'generated-tests'
* Made the clean target not fail if the 'generated-tests' directory
doesn't already exist.
llvm-svn: 175624
autoconf and CMake flavours both updated to auto-generate files for use
in cpp11-migrate's LIT tests.
Auto-generated files are placed in the build directory under
test/cpp11-migrate/autogen. The directory structure past this point
mirrors the structure in the source directory under test/cpp11-migrate.
A lit.site.cfg is generated in test/cpp11-migrate/autogen to describe
the new test suite. When LIT runs, it runs the standard testsuite and
now also the auto-generated testsuite.
llvm-svn: 175544
cpp11-migrate now contains the loop convert transform code and tests.
Cleaning up the old code/tests and updating build system files as
necessary.

- Added directory structures and build system files for the new tool.
- Extremely basic implementation of tool performs only an initial syntax check.
- Basic tests ensure syntax test works as expected.
llvm-svn: 169983
A new Clang-based tool which converts for loops to use the range-based
syntax new to C++11. Three kinds of loops can be converted:
- Loops over statically allocated arrays
- Loops over containers, using iterators
- Loops over array-like containers, using operator[] and at()
Each transformation is assigned a confidence level by the tool. The
minimum require confidence level to actually apply the transformation
can be specified on the command line, but the default level should be
fine for most code.
Like other tools based on RefactoringTool, it is easiest to use this
tool with a compilation database.
llvm-svn: 162627
Loop Converter Skeleton - array-step-1
Added a check to loop increments - array-step-2b
Added a check on the loop's condition expression - array-step-2c
Finished array matcher - array-step-2
Retrieved matched nodes - array-step-3
Analysis for array loop indices - array-step-4
Added checking for naming and variable scope
Added confidence level and count-only command line args
Added aliased variable elision
Added support for iterator-based loops
Added support for single-iterator loops which call end() repeatedly
Added support for converting array-like containers
llvm-svn: 162610
With this we can build and test the remove-cstr-calls tool which should
serve as a good example of how to add tools and their tests to the
repository.
